Computer and Video Games has word from Valve to expect the announcement of another DLC pack for Left 4 Dead for both Windows and Xbox 360 before the summer is over. "We plan to keep supporting Left 4 Dead 1. There will be some announcements coming before summer's out about what's coming there, and then we haven't shown everything that's in Left 4 Dead 2 yet," is what they hear from Valve's Doug Lombardi. "I think 8, 9 months from now once everything's been out for a while and everyone's had time to see the complete product of Left 4 Dead 2 and see continued support for Left 4 Dead 1, they may sort of see what we were up to and what the method of our madness was there." He also says that the release of Left 4 Dead 2 will be preceded by a playable demo.
